WebPlus X5: How to

So basically I designed a website for the shop I work in on my home computer.

Now that I finished it, I suggested they purchase webplus X5 so they'd be able to edit it themselves once I leave. (I use X2 at home).

So I transferred the webplus document and all the images I was using on my USB stick and put them on the shop computer.

However, any time I open the file it always says it can't find the link to the images. (i.e. the link to my folder and computer at home). However, all the images appear fine when I click "No to All" when it asks me if I want to choose new folders for all the images. How do I get it to stop trying to find the images on my computer back home when it doesn't even need to?

Also, it says that numerous fonts I used aren't available and to let WebPlus automatically pick fonts to use or for me to choose replacement fonts manually. I did the latter and then went through all the pages and changed the font of each textbox to the basic "Arial" font. But after saving and reopening the site, it comes up with the same message, despite me having already changed all the fonts the previous time. How do I stop this?

EDIT: P.S. How do I edit the title of this thread? I have somehow managed to only type the start of the title, or the computer has cut it off.
